Abstract

A device for controlling an actuator/solenoid valve output stage, for a vehicle, including: a terminal to receive an enable signal via an interface to an application unit, the enable signal assuming enable/disable states to enable/disable output stage control; a first suppression terminal to receive a first suppression signal via a monitoring unit interface, the first suppression signal assuming a first authorization/suppression state for authorizing/suppressing output stage control; a second suppression terminal to receive a second suppression signal via a second monitoring unit interface, the second suppression signal assuming a second authorization/suppression state for authorizing/suppressing output stage control; an output terminal as an interface to the output stage; and a linking unit to provide a control signal for controlling the output stage to the output terminal for the enable signal, and the first/second suppression signal has the first/second authorization state. Also described are a related method and actuator circuit.
